O.K., now I get it.
Like kleins for sidecuts, channels for arc-joint pliers, etc.
On the branch circuit tap approach appearing reasonable, it seems that a lot of Code requirements provide a wide margin of safety. On the other hand, what do you gain by using a 14 tap off of a 12 BC conductor? Mainly a little easier time of it tucking the device back into the box. If the box is so crowded that this is a real problem, maybe it's time to replace the box.
